Solving twostep linear equations: $ax + b = c$, ${x \over a} + b = c$  Linear Equations
Solving twostep linear equations: $ax + b = c$, ${x \over a} + b = c$
Solving twostep linear equations literally means solving the equations in two major steps. First, we need to isolate the unknown "x" to one side of the equation. You can then solve the "x". To complete these two steps, you may need to perform addition, subtraction, division, multiplication, cross multiplication, and so on. When the equation has fractions, you may also need to find the common denominator before proceeding further. Seems complicated? No worries! You will learn all the tricks in this section.
